Bar magnets, in various sizes and strengths, are ideal for sensors with unipolar magnetic characteristics. The ring magnets, with alternate South and North poles on the outside diameter, are especially useful for sensors with bi- polar magnetic characteristics. (For more information on magnets and methods of magnet actuation, see Application Data.)

There are several factors to consider when choosing a magnet. The most important is gap distances. There must be adequate magnetic gauss to op- erate the sensor at the correct distance. By using the maximum operate magnetic gauss characteristics (see sensor order guides), you can determine which mag- net(s) will operate the sensor. Other im- portant factors include temperature range and the physical environment of the application.
